Singlespeed & Fixed Gear - Threading a Fork

I need to have a fork threaded further down and cut. I have been to two shops in Portland and both seemed to think it was a difficult/expensive thing to do. So my question in does anyone here know of a good shop in Portland that could do this for me for a fairly reasonable price. I was quoted 60 or more.
-Thanks

i payed $20 here in iowa...

i would make a post in the frame builder forum. several guys over there have the tools and/or may be able to point you in the correct direction.

The bike co-op I volunteer at charges $10 per cm. It's hard work and prepared to pay a lot to get it thread.

Which shops did you go to?

with the right tool and some cutting fluid this is not such a big deal

I went to Universal Cycles(they told me they didn't have the tools to do it) and I went to 21st Avenue Bicycles. I was going to call around tomorrow but figured if someone had a good shop to recommend I would save the time.

You could try CCC on NE Alberta, they were pretty cool last time I went in. Recyclery probably doesn't have the tools, though I am not entirely sure, only been to the one on 11th.

You could even try Bicycle Gallery, but I have not really been in there, and they tend to be kind of expensive as well.

I haven't lived in Portland for a while, so I might be out of date. :(

Or you can just buy a new fork.....if your not attached to the one you have. Sorry $60 is really steep. IMHO If you have a car check out Home Depot or Lowes!!! I'm sure they have the tool for you for WAAAAY less no joke! They can cut threads/pipe or can refer you to a plumber who can. Its really just a piece of pipe.

it is just a piece of pipe, but it is not just pipe thread.

It's a liability issue as well, when forks are threaded by a shop, it cut material away rather than rolling/pushing the tube to form the thread in the factory. It makes the steerer tube thinner at the threaded area and it might break when used for awhile...shops don't want to take that risk.

Your absolutely right what the hell was I thinking?
Sorry....you have to pay for the correct process

vixtor is right. many shops will refuse to do this, its not worth their business to have to deal with a fork that broke due to their cutting - threaded forks generally ship with slightly different thicknessed walls so the threads dont cut too far. shops will, however, add threads to an existing threaded fork.

I've read (on BF) that threadless forks shouldn't be threaded due to the chance of them failing. If your steerer does fail, it will almost certainly result in a swift painful crash.

My advice is to get a threadless headset and stem. Or just get a threaded fork if you can find one cheaper than the headset + stem.

unless the steerer is butted, all standard ISO and JIS steerers have the same wall thickness. the OD is 25.4mm and they all use a 22.2mm quill stem. (french and several other bikes differ)


if you really wanted, you can thread a threadless fork that uses the same size tubing. there will be no issues other than rolled vs cut threads but frame builders have been cutting threads without issue for years.

It's just a die cutter. 60 bones is wayyyy too much. Offer the mechanic a six pack.
